It's similar to what Miley Cyrus did in the "We Can't Stop" video-- a bounceless attempt at twerking by an insufficienlty- upholstered (read bony-assed white girl) that looks more like a crazy calesthenic than anything remotely attractive. Unless you're really hard up. See the beurk entry for expalnation.
"Yeah, but the beurk-twerking is really just sad; she looks like a mariontte trying to hump a piece of furniture. Next!"
